VALVE.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed June 7, 1911. Serial No. 631,825.

To all whom t may concern Be it known that I, NEAL 7. WHITBEOK, acitizen of the United States, residing at Detroit, county of Vayne,State of Michigan, have invented a certain new and useful lmprovement inValves, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

This invention relates to valves and an object of the invention is asimple and efficient means for preventing leakage around the stem oroperating rod and avoiding the necessity of packing the stem withwicking or like material as is usual with valves of the ordinary type.

Another object of the invention is an effi'- cient and inexpensive meansfor preventing a rotation of the valve disk or ring on its seat duringthe rotation of the stem to seat or unseat the disk.

The novelty of the invent-ion is in the peculiar design and arrangementof the vari-` ous parts, as hereinafter more fully del scribed andclaimed, whereby these and' other obj ects may be accomplished at aminimum of expense in labor and material.

In the drawings- Figure l is a vertical section of a valve embodying myinvention. Fig. 2 is a section on line x-az of Fig. 1 showingthe methodof attaching the traveling` nut to the valve head.

Similar characters refer to similar parts throughout the drawings andspecification.

The body 1 of the valve is provided with a cap or bonnet 2 which has anextension or neck 3 through which thestem or rod 4 enters the body. Theextension 3 is provided with a cap nut 5 and has a tapered'seatfor thecone 6 which is preferably formed integrally with the stem. rlhe conemay be formed with one or more circumferential grooves 7 which arepreferably filled with graphite or analogous material shown in sectionat 8. In fillin the grooves with graphite, the entire sur ace of thecone to a greater or less extent becomes covered with said material andtherefore, for ordinary use, it is unnecessary to grind the cone in itsseat as the graphite will lill all tool marks or other irregularities inthe two contact surfaces thus providing an efficient packing for thestem. For use with high pressure systems, however, it is advisable togrind the cone in its seat as a better contact between the two surfacesis thus produced and greater efliciency attained. The cone is held onits seat by the sleeve or gland 9 on the stein 4 which has ascrew-threaded engagement with the cap nut 5. The upper and large end ofthe cone has an annular groove 10 for holding a soft metal ring orwasher 11 against which the end of the sleeve 9 engages. The slee-ve isprovided with a lock nut 12 by means of which it is firmly held in itsset position. The sleeve provides a means for taking up wear and theseat is made somewhat longer than the cone in order that the cone may beadjusted in vertical position as it wearswithout decreasing the i amountof surface in contact with the seat.

The ring or washer l1 may be made of the same composition as the valvedisk but is preferably made of soft metal, as lead, and in use itprovides an eiiicient means for preventing leakage between t-he stem andsleeve 9 should, by any chance, leakage occur between the cone and itsseat. Also, should this last mentioned condition arise, leakage can notoccur between the cap nut 5 and the neck 3 or between the nut and sleeve9 as the surfaces of the threads in both instances are held iirmly inengagement by reason of the strain produced therebetween by screwing thesleeve against the washer 11.

On the upper end the valve stem or rod 4 is provided with a hand wheel13 and at the lower end has screw threads 14 engaging the traveling nut15 which in turn is secured to the valve head 16. The valve head isprovided with a central annular chamber 17 into which an end 18 of thetraveling nut is inserted and held in place by the two pronged pin 19which passes -through openings provided in the head 16 and engages in anannular groove 2O in the end 18 of the traveling nut. The valve headcarries a ring 21 of the ordinary patternand material which may be heldin place by any suitable method as the nut and plate shown in Fig. 1.

The valve head is also provided with studs 22 extending upwardlytherefrom each side of the nut 15 and loosely engaging in the holes Q3provided therefor in the cap 2. The studs may be screwed or pressed intoplace in the head and prevent a rotation of the valve ring on its seatwhen the stem 4 is rotated to seat or unseat the valve. The nut 15 isalso held from rotation in the head 16 by the lugs 2A through openingsin which the studs 22 pass.

In operat-ion, the rotation of the'stem l by the hand wheel opens orcloses the passageway through the body by raising or lowering the valvering away fro-1n or toward its seat by reason of the screw-threadedengagement of the stem with the traveling nut and the studs 22 riding inthe holes 28 prevent a rot-ation of the valve head, as heretoforementioned. The usual method of preventing such rotation is in providingthe nut or similar member with wings or lugs which ride in slots orgrooves formed in the bonnet or body by breaching which method involvesconsiderable expense over the method herein disclosed.

The method herewith shown of preventing leakage around the stem of thevalve, while simple and inexpensive, is very eiiicient in operation andavoids the necessity of frequently repacking the stem as is requiredwhen wicking or like material is used.

While the body 1 shown in the drawing is of a type more particularlyadapted for use with radiators and the like, I do not wish to limitmyself to such design as the novel features herein disclosed areadaptable for use in valves of various other types and forms, thealterations, if any, being of such nature that any one possessed ofordinary mechanical skill may change the size` ferm, or position of theparts to suit the required conditions.

What I claim as new and desire to secure by Letters Patent of the UnitedStates is- 1.
